Round-Cut Diamonds and More Available Before Valentine’s Day

The demand for round-cut diamonds erupted in the early 1900s, replacing the previous favorite, the Old European cut. Several examples of the round-cut diamond will highlight this upcoming Bid Global International Auctioneers sale, including a 10.28-carat unmounted diamond. This piece earned a “D” color grade, the highest grade. This indicates the diamond shows next to no unwanted color, even under magnification.

Another popular cut represented in this sale is the heart-cut diamond. The cut’s history can be traced back to the 16th century. Queen Elizabeth I was among its early adopters.

Both of these examples earned a VS1 clarity, meaning any imperfections are very slight and unlikely to appear without magnification. View each of the lots and register to bid on Bidsquare.
